MECHANISM FOR OPERATING FLUSH-VALVES.

Specification of Letters Patent.

Patented June 22, 1909.

Application filed December 14, 1908. Serial No. 461,552.

To all whom it may concern:

Be it known that we, JAMEs M. YOUNG and Fnnonnrok W. Ronnnrsrmw, both residents of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Mechanism for Operating Flush-Valves, of which the following is a specification.

This invention relates to mechanism for operating flushing valves of water closet tanks and the like. a

The object of the invention is to provide mechanism for this purpose which is of simple, strong and compact construction and which comprises a minimum number of parts, and especially which has only a single means of attachment or connection to the tank, thereby particularly adapting the fit-' ting to tanks of metal, porcelain or other material to which the attachment of parts is diflicult and costly.

For'the attainment of the foregoing and other objects the invention comprisesthe construction and arran ement of parts hereinafter described and c aimed.

In the accompanying drawing Figure 1 is an inside elevation of the valve operating mechanism with the parts in position to open the flush valve; Fig. 2 is a similar view showmg the parts in position to keep the flush va ve closed, the set screw'being omitted; Fig. 3 is a vertical section taken through the operating shaft or spindle; and Fig. 4 is an end elevation of the device.

In the drawingthe tank wall is indicated by 2. This may be metal, Wood, porcelain or other suitable material. The flush valve operatin mechanism comprises a fitting consisting 0 a plate 3 arranged to lie against the inner face of the tank wall and having projecting outwardly therefrom the hollow projection or sleeve 4 which is adapted to proj ect through a hole in the tank wall and at its outer end is threaded to receive a cap nut 5 which serves to secure the fitting to the tank and also to givethe finish on the outside of the tank. A projection 6 on the fitting'enters a suitable slot or hole in the tank wall and prevents the fitting from turning. The

nut 5 is the only fastening means necessary either direction.

one side of the opening thcrclhrough with a fulcrum 8 for the valve operating lever 9, the latter having its free end. connected to the rod 10 which carries the usual flushing valve, not shown. On its opposite side said plate 'is provided with the forked guide 11 for i a sleeve 15 adapted to fit on the square inner end of shaft 13, and secured thereto by suitable means such as by set screw 16, or cob ter pin, and fitting up against a shoulder 17 on the plate 3. This sleeve is provided with a forked ,arm 18 in which is mounted a roller 19 adapted to contact with cam faces 20 and 21 on the valve operating lever 9. Preferably two suchoam faces, reverscly arranged, are provided in order that the lever 9 may be lifted to open the flush valve irrespective of the direction in which the operating lever 14 is moved, as is apparent from Fig. 1. Suitable stops are provided to limit the movements of the actuating shaft 13 and revent the roller 19 from moving too far 1n either direction. The stops shown comrise a projection 22 on sleeve 15 moving between-a pair of projections 23 on the plate 3.

The construction and operation of the mechanism will be readily understood from the foregoing description in connection with the drawings. The flush valve is opened by moving the operating member 14 in The mechanism described has only a single connection with the tank, this being by means of the threaded sleeve 4 and nut 5. Both the center of the operatin shaft 13 and also the center on which the valve operating lever 9 is fulcrumed are carried by this one fitting. The consequence is that the device can be secured to a tank with a minimum number of attachments, particularly adapting it to metal, porcelain and similar tanks to .which attachments cannot be easily secured. With all prior valve mechanism the tank or Wall had to have separately attached thereto at least 1.' Mechanism for operating flushing valves, comprising a plate'for. attachment toli g f tatably mounted n the the inside of the tank and provided with an opening for an operating shaft and with a, lever fulcrum center and @with its axis substantially parallel to the axis of said opening, a lever mounted on said fulcrum, and an operating shaft rohole in the plate and provided on its outer end-with an operating member and onits inner end with an arm having 0 erative engagement with the lever. 2.
